Ultramar’s Odyssey XLD Synthetic 5W-40 product has moved "to a new level of performance," the company says, as a premium offering in the light-to-heavy transport market. This fully synthetic engine now meets or exceeds the API CJ-4/ SM industry standards.

It also meets or exceeds the manufacturers requirements for light-duty diesel engines such as Powerstroke & Duramax; and heavy-duty diesels such as Caterpillar, Cummins, Detroit Diesel, Mack, Navistar and Volvo.

Ultramar says it offers enhanced fuel economy potential over conventional 15W-40 engine oils.
